Valenc evaluates substance and mixture data using the published GHS rules for your selected jurisdiction, displaying the specific rule behind each result. Classification is never processed by a language model. Identical inputs always yield identical results, allowing reviewers to see what triggered a hazard, where thresholds applied, and where human judgment is required.
An SDS reports, but does not create, a hazard classification. Valenc uses the underlying data and applies regulatory rules before authoring begins.
The substances in the product and their concentrations or concentration ranges.
The classification of each substance, including harmonised classifications required by the jurisdiction.
Flash point, physical state, pH, and other measured values relevant to certain hazard classes.
The rules engine evaluates these inputs directly and does not infer hazards from free text.
A single substance is classified based on its own data. A mixture is classified using its ingredients, their concentrations, and the jurisdiction's mixture rules, including additivity formulas for acute toxicity, concentration cut-offs for each hazard class, and bridging principles when relevant test data exists. Allergen and restricted-substance screening are performed concurrently.
A mixture is not classified by simply copying all supplier hazards to the final product. The rules determine which hazards apply, and Valenc displays the specific rule used.
With the same approved inputs and rule set, Valenc consistently returns the same classification. The engine encodes the published rules for each jurisdiction, using UN GHS Revision 11 as the reference and layering national implementations such as OSHA HCS 2024 (United States), CLP (EU), WHMIS under the amended HPR (Canada), and NOM-018 (Mexico), covering over 80 jurisdictions in version 1.0.
Each result is stored with the rule and inputs that produced it. When an auditor or customer requests justification for a hazard statement, the answer is immediately available on screen.
Supplier data may not always provide an exact concentration. If a range spans a regulatory cut-off, classification cannot be resolved from the available data alone. Valenc flags this conflict rather than selecting a value without review.
A reviewer can see the component, the concentration range, the threshold crossed, and the relevant hazard class, and can make an informed decision. This compliance decision should be transparent. Classification software must make uncertainty visible, not conceal it.
Select a jurisdiction and Valenc evaluates the same product data under its rules. The composition and properties remain with the product; only the regulatory framework changes. You can compare classifications across the US, EU, and Canada without recreating the product record.
The classification queue highlights products requiring a decision and the reason: a range crossing a cut-off, a missing property required by a rule, or a substance with a new harmonised classification. Each item answers three questions: Which product or component needs attention? What issue was detected? Why could the rules engine not resolve it? This allows reviewers to focus on judgment rather than searching through every product.
Valenc does not allow an AI writer to generate hazards during SDS drafting. The product is classified according to the applicable rules first. The result then populates the SDS, with hazard and precautionary statements sourced from a curated GHS phrase library in over 25 languages. Classification determines the hazard; authoring communicates it.
GHS classification is the systematic evaluation of a substance or mixture against defined hazard criteria to determine applicable hazard classes and categories. These classifications inform the hazard communication required on both the SDS and product labeling.
Valenc classifies mixtures by analyzing the composition, ingredient classifications, concentration ranges, relevant physical and chemical properties, and the mixture rules of the selected jurisdiction. The deterministic rules engine evaluates these inputs to assign the correct classification.
No. While AI is used to extract data from supplier documents and review drafted content, all hazard classifications are determined exclusively by deterministic rules, not by probabilistic models or AI-based predictions.
Yes. Every classification clearly displays the specific rule applied and the input data that triggered the decision, providing full transparency and traceability for each result.
When a concentration range spans a regulatory threshold, Valenc flags the conflict for review rather than selecting an arbitrary value that could alter the classification, ensuring compliance and informed decision-making.
Yes. Valenc enables you to evaluate the same product record under the regulations of each jurisdiction in which you operate. Version 1.0 supports classification across more than 80 global jurisdictions.
